Fetal movement will usually be felt regularly after the 20th week of pregnancy. Any change in fetal movement (other than a 1-2 hour sleep cycle that some fetuses have) should be discussed with your physician. Decreased or absent fetal movement may be a sign of fetal distress. Kick tests (fetal movement counts) are used to monitor fetal wellbeing. You should monitor fetal movements (not just kicks) over a period of time (30-60 minutes). There is no right or wrong number of movements. You are trying to establish a baseline of fetal movements for your baby.
Fetal movements are the kicks, rolls, and hiccups of your unborn baby. You may start to feel these movements when you are 20 weeks pregnant. The movements grow stronger and more frequent as your baby grows. Fetal movements show that your unborn baby is getting the oxygen and nutrients he needs before birth. Fewer fetal movements may signal a problem with your baby's health.
